Waterproof Drone

The worlds first fully waterproof and buoyant quadcopter drone just got even better.

Enhancing and extending the features of the previous SplashDrone 3. The latest SplashDrone 3+ is the most reliable and versatile waterproof drone yet .

Coupled with several different payload options such as Cameras combined with Payload Release Mechanisms. SplashDrone 3+ can be adapted for a wide variety of uses .It is an all purpose,all weather,waterproof flying platform.

Power and maneuverability to fly in winds up to Beaufort Force 4 (18mph/28 kmh) with gusts to Force 6 (31mph/49 kmh).

Tough & Waterproof

The SplashDrone 3+ fuselage is made from durable 3mm reinforced ABS to ensure a perfect waterproof seal.

Each drone undergoes at least two pressure tests during production for 100% waterproofness. All parts, both inside and out, are corrosion resistant and designed for use in marine environments.

New access hatch lid with air pressure equalization allows altimeter accuracy without permitting water entry.

Waterproof Drone Smooth Control





PL2 release mechanism is capable of carrying items including long fishing lines and casting baits to any target location, in the surf or in unreachable waters. (The max flight range of Splash Drone 3+ is up to 1.6 km+.)


PL2 is manufactured from high precision CNC aluminium and stainless steel. The max payload capacity is 1kg. It is capable of carrying more than 10 hooks and baits in one delivery. It can also be used to carry a life preserver or life jacket for surf rescue.


Instead of releasing baits unintentionally like the third-party-made bait dropper, PL2 enables precise surfcasting with a switch on the remote controller of Splash Drone over a long range.


The payload release is integrated with a waterproof HD camera, thereby eliminating the requirement of a second camera. The camera can be tilted within a 90° range. Real time video from the camera can be viewed using an FPV monitor up to distances in excess of one kilometre. The camera is also able to capture a clear view below the water surface, thereby helping you to easily find the optimum fishing spot.


The whole mechanism is as waterproof and salt water resistant as the Splash drone 3+. The quick attach design allows it to be mounted onto the drone in a few seconds.

The PL3 is a new, innovative and powerful add-on which increases the versatility of the SplashDrone 3+. Technically, the PL3 is a combination of the waterproof full HD camera and the original payload release mechanism.

Now with the PL3, and compared to the previous model (PL2) , you now have the added benefit of a gimbal mounted camera, as well as being able to record your payload release or rescue operation to a MicroSD card, which was not possible before. The camera is stabilized by 4 rubber damping balls, ensuring the recording of steady footage while carrying and dropping a payload. It is very simple to use, you can tilt the camera from the remote controller to view what's in front of the drone, and also where your items are to be dropped. This can be very convenient, especially during rescue or life saving operations with live video back to the FPV screen which is in the palm of your hands.

Thanks to the PL3, the SplashDrone 3+ is now able to offer you a more precise release of fishing traces or bait, or lifesaving equipment over a wide radius from your position, and is fully under your control. The efficiency is increased beyond your imagination.
